Abstract: Aspects relate to digital imaging. An example method includes receiving a first image frame of a scene captured by a first image sensor. The method also includes receiving a second image frame of the scene captured by a second image sensor. The second image frame is captured concurrently with capture of the first image frame. The method also includes receiving a third image frame of the scene captured by a third image sensor. The third image frame is captured concurrently with capture of the first image frame. The method also includes generating a combined image from the first image frame, the second image frame, and the third image frame. The combined image includes a first field of view that is wider than a field of view of the first image frame.

Abstract: Aspects of the present disclosure relate to an adjustable light projector for active depth sensing and flood illumination. An example device includes a light projector that includes a light source to emit a light along a first direction and a diffractive element positioned in a path of the emitted light along the first direction. The diffractive element includes a diffractive optical element having a first refractive index and configured to project a distribution of focused light from the emitted light during a first mode. The diffractive element also includes a diffusion element having a second refractive index and configured to diffuse the emitted light during a second mode.

Abstract: Techniques are disclosed for generating a high resolution image from a plurality of images captured from a plurality of sensors. The pixels in one sensor have at least one of different size, shape, or orientation than pixels in another sensor. The difference in size, shape, or orientation of the pixels and the interconnection of pixels on respective sensors provides a high level of certainty that there will be sufficient difference in the captured images, with limited loss in image content, to generate a relatively high resolution image from the images captured by the respective sensors.

Abstract: This disclosure provides systems, methods, and apparatuses for sensing a scene. In one aspect, a device may illuminate the scene using a sequence of two or more periods. Each period may include a transmission portion during which a plurality of light pulses are emitted onto the scene. Each period may include a non-transmission portion corresponding to an absence of emitted light. The device may receive, during each transmission portion, a plurality of light pulses reflected from the scene. The device may continuously accumulate photoelectric charge indicative of the received light pulses during an entirety of the sequence. The device may transfer the accumulated photoelectric charge to a readout circuit after an end of the sequence.

Abstract: Aspects of the present disclosure relate to depth sensing using a device. An example device includes a first light projector configured to project light towards a second light projector configured to project light towards the first light projector. The example device includes a reflective component positioned between the first and second light projectors, the reflective component configured to redirect the light projected by the first light projector onto a first portion of a scene and to redirect the light projected by the second light projector onto a second portion of the scene, and the first and second portions of the scene being adjacent to one another and non-overlapping relative to one another. The example device includes a receiver configured to detect reflections of redirected light projected by the first and second light projectors.

Abstract: Natural-scene light is polarized so the light exiting the polarizer and entering a glass assembly has a first polarization. Light having a second polarization substantially orthogonal to the first polarization is launched into the glass assembly and directed normal to the glass assembly and into a zone plate assembly, along with the natural-scene light. A first plurality of electric fields is established in the zone assembly to form at least one zone plate that modulates the launched light without modulating the natural-scene light. The first plurality of electric fields is disestablished and a second plurality of electric fields is established in the zone plate assembly to reposition the at least one zone plate in the liquid crystal plate. Disestablishment and establishment of electric fields is repeated at a sufficient rate so that an image defined by a number of pixel spots formed on a retina is perceived by a viewer.
